How different options affect cold starts?

[patryk-smc]

Hello everyone,
I'm currently working on optimizing my application's cold starts, and I've been researching various strategies online. I believe I've already implemented most of the recommended approaches, but I'm curious about a few additional options available in Esbuild that could potentially have a greater impact.

These options include:

1. Enabling minification
2. Utilizing the "external" feature
3. Setting the format to "esm"
4. Removing legal comments from the code using the "legalComments: none" setting

I'm wondering if anyone has experience with these options and whether they can significantly improve cold start times. Any insights would be greatly appreciated.

Thank you!
